Answer:
x=13
Step-by-step explanation:
because they're alternate adjacent angles:
5x=78-x
6x=78
x=13
By pythagoras theorem if a and b are sides of the right angle and c is the hypotenuse then
a^2 + b^2 = c^2
3^2 + 4^2 = c^2
9 + 16 = c^2
c^2 = 25
c = 5
Not sure what the "T" is but if you were trying to solve or factor the parenthetical term:
-4t^2(t-2) is the factored form and the zeros or solutions would be when:
t=0 and 2
If the "T" was a leading coefficient of "t" the above still holds true except:
-4t^3(t-2), but the solutions are the same...
Answer:
678.58 ft^3
Step-by-step explanation:
V=πr2h/3
25.12/12.5663706 = 1.99898608
1.99898608 X 3 = 5.99695826
h= 6ft
6/2 = 3
6 * 3 = 18
V = π * 6^ * 18/3
V = 678.584013
